This is large, this is big, this is HUGE! This morning we're going for a drive to pick up more material for your battery shelve. Also, there was a box at the front gate containing the new Noark circuit breakers. Wow, they look massive! We take a closer look and start preparing the aluminium hull around the shelve.

I thought the same thing to use MDF / HDF board with thickness 3mm or thicker or use cutting board (those that are 1-3mm and flexible) should you break both the positive and negative side or just one? and have you intended to use reached to improve the contact as a grease and which also prevents oxidation

If the cells are to sit directly on the aluminium shelves be very careful. With the cells connected in series any break in the blue plastic on the underside of two cells will risk a short out between cells. I nearly fell into this trap as my cell supplier did not insulate the cell undersides. I would suggest using some form of extra insulation layer added between shelves and cells would be sensible.

Originally I had planned to put the battery pack directly on an aluminium sheet with heat pads underneath for use during winter conditions. Unlike Andy some of us have to allow for low ambient temperatures. The sheet will even out the heat distribution but I need to guard against heat insulation between the aluminium and the cells. For the moment I have covered the aluminium with a thin self adhesive wrapping. This effectively double insulates electrically but hopefully still allows some heat transmission. My battery box (a small camping trailer to allow portability) is well insulated. Although heat transmission (when required) might be impeded slightly by the wrapping, the surrounding insulation will make sure that the heat gets to the cells eventually. For hot weather the trailer has a lifting cover to allow airflow but these cells don't seem to heat up much unless they are charged/discharged at very high currents.

I'd seen a comment elsewhere that you should place extra insulation between cells when compressing them to ensure they don't make any electrical contact. I was highly sceptical that the aluminium case was connected to either terminal. But I've just measured mine and the case is very much -ve. So insulating the bottoms will be essential.

Nice video. It looks good. I have only few suggestions 1. Don't take out those support bracket n bottom part of shelfs ..i would not remove them..it make shelf stronger and you need it..aluminium is not all that is needed 2. Use some kind of protection for those bus bars (even one buss bar usually + is ok ) so there is no accident touch.. screw might fall down..or what ever.. 3. place some protection(not conductive take or something similar) below those breakers ..in case one contact will get loose there is no way it will touch AL shelf .. 4. Keep up hard work.. i'm doing similar project myself...new inverter, charger and cables coming..so a lot of work is waiting for myself as well :)

I have a 250a zjbeny and yeh its massive lol. As for your lugs they look like cheap ebay thin pressed tube ones. For such a decent batery bank i would be sourcing some decent branded lugs like Cabac for example as they are twice as thick as the cheapies. I have tossed all my cheap lugs and only use decent ones now days. I would still insulate around the busbar cut out JUST incase. its $1 worth of hose or rubber and saves a potential short if something fell down there as i have learn't never assume that something will be fine lol.

Not worried about the shelves conducting? I'd insulate the shelf tops. Also did you do any research on air arcing between the bars themselves? You could then potentially have arcing from bar to shelf and back to bar. Probably more than fine with the finger distance but something to research. I'd have the bus bars further apart to make it virtually impossible to short by any metal tool.

You should add plastic or rubber edging to the aluminum shelving near the buss bars. When current is flowing a magnetic field will attract to the shelving. Mostly this not be a problem, but in rare cases (like when the humidity goes below 20% or during thunderstorms) current could jump the gap if is uninsulated. To stop it I used RTV electrical silicone and split spiral plastic conduit. (Like the kind used in automotive cable harness)

Why do you need 550 amps of circuit breaker? Lightening? Expensive disconnect?

All you need is an excessive amount of solar panels. Do they have sunny days in Europe? 😄 ( Don’t mind me. I’m just a somewhat uninformed American.) Is Brisbane Australia?

on occasion. i remember that in England in 1976 it did not rain for 3 months. this was unheard of in history. records that went back many hundreds of years were broken. However no one blamed global warming because then like now it does not exist.

: ) cool . thanks ... for me , your videos are interesting because they point to what might be an ideal setup if money were no object . off grid house / car / life - requiring minimal ( preferably NO ) engagement with damaging industries is the grail . please don't gloss over the prices of stuff - they matter !.. and an awareness of environmental impacts would , I think raise the relevance of your channel . just sayin' ...

Thanks for your comment. That is great thinking and totally agree with you. I rather spend more money on things which last and also be as sustainable as possible which is very hard in a carbon fuelled economy.
